The worst feeling a man can go through is the feeling of not being valuable, like if you died tomorrow, nothing would change, life would continue exactly as it has today, or if you were on your deathbed, you would have nothing to show for your life.
I’ve suffered with this, and known others to as well, the feeling of being invisible, not in the physical sense, but in the sense you feel nobody understands you, and your life has no value to it.
We’ve lost too many good men to this, we need to be there for each other more, and check up on those close to us, even if they don’t need it.
